DISADVANTAGE OF USING PSA?

Hi Everyone,
Can anybody tell me what is the disadvantage of using PSA ?

Hi........
As disadvantage of PSA u can say...........
1) Memory space will be occupied..........
2) Diplication of same records in the BI side.............ie PSA and agsin in Data targets.........
But still I will say............loading through PSA is good.............since.........if something goes wrong.......and suppose u hav to load the data again.........no need to do the Extraction again..........data will be in BI side only.........it will save time.............Moreover .........if someone by mistake delete the data from the target........data will not be lost...............since there is a back up in PSA..............
If u want save the memory space.............Just everyday delete PSA records older than 10 days...........If there r many datasources.............just create a Process chain.............and run it end of the day............ie completion of the loads............then it will solve ur problem........

Disadvantages of using "0" zero as first value in a generated sequence

Does anyone have any experience with the benefits/disadvantages of using a value of 0 "zero" as the first value generated in a sequence that is also populated in a table. My past experience has always used the values of 1 "one" as the first generated value from a sequence.
Thanks

Benefit: You get use one "more" number from the list of values that can possibly be generated by the sequence. If you are start from '1', you have missed out on '0' :-)
Disadvantages: If any of the queries have predicate like "sequence_generated_column_value > 0" and that your sequence starts from zero, the record with sequence_generated_column_value=0 will not appear in result set for that query (assuming it satisfies other conditions).
May be there are many mores benefits/disadvantages to add to this list :-)

What are the drawbacks or disadvantages of using LSMW

Hi All,
Can anyone tell me what could be the possible disadvantages of using LSMW and also some disadvantages of BAPI.
Regards,
MD.

Hi MD.
I would like to suggest a couple of disadvantages of LSMW.
Here are a few scenarios------>
1. Time consumption -
> IDOC processing plays a vital role. The changes made to the IDOC is therefore very time consuming.
2. In term of BAPI -
> Incomplete in terms of input fields of a particular transaction, rather it is not always complete.
3. In terms of Direct Input -
> No enjoy transactions and incomplete in terms of input fields of a particular transaction.
4. In terms of Batch input -
> Slow in terms of new recordings to be done, but BDCs are much simpler in that terms.
This factor also depends upon the user settings, The kind of processing which is foreground and background.
Hope that's usefull.
Good Luck & Regards.

What's disadvantages when using bind variables always in java?

Hello everyone .. Could someone tell me what's the disadvantage when using bind variable in java ? I heard it somecases since before.. Thanks in advance!

99% of the time, you should be using bind variables. If you have columns which are highly skewed, however, you may want to consider using literals (assuming CURSOR_SHARING=EXACT), since that may allow the CBO to make a better decision.
If you have an orders table, for example, you may have a status column that specifies whether the order is complete, in transit, or new. If you've been running for a while, 99% of your orders will be complete, so
SELECT COUNT(*)
FROM orders
WHERE status = :1should do a full table scan if you specify 'COMPLETE'. If you passed in 'IN TRANSIT', though, an index scan might be more appropriate. If you want to pass in different values and get different query plans, you need to use literals. 99% of the time, though, you want the same plan, so you want to use bind variables.

Advantages and Disadvantages of using Nintex forms. is this product useful?

So my company has decided to start developing using Nintex products, we initially had Nintex Workflow and now they are thinking of purchasing Nintex forms. and i was asked to start trying it out.
I am currently midway through the development of a sharepoint app and i really like the REST APIs available in sharepoint 2013 as they enable me to develop using javascript and HTML5, quite basic stuff but very powerful.
Now they are asking me to try this black boxed product out, so i have to waste a couple of days on this...
I watched a couple of youtube videos and all they brag about is how easy it is to drag and drop components on the screen and visually design a form when this is the feature i care about the least. To me what counts most is how easy it would be to customize
the form to do something that was not foreseen in the black box product.
What are the advantages/disadvantages of using Nintex forms over using Javascript/HTML 5/Sharepoint REST ?
many thanks

With a developer hat on, I can appreciate that custom solutions can potentially be easier to build and manipulate, as you are not adopting anyone's framework and may have less constraints building with a blank canvas each time.
With a business owner or business analyst hat on, there are many advantages for using a product or application to build repeatable solutions such as forms.
SharePoint can quickly fall into demise if users (end user or super user) have free reign to build and deploy custom solutions, as they may or may not follow a consistent build pattern, and even other super users or developers can have difficulties interpreting
and adopting solutions, should someone (such as yourself) leave an organisation.
This is where products can provide significant return on investment. Products such as Nintex are built by experts in more than HTML, REST and JavaScript, but SharePoint as well. They provide a framework which ensures Form and Workflow designers follow a consistent
approach, and each solution can quickly be viewed and interpreted by other users.
Data gathering (forms) and workflow are also usually repeatable and work. I.e. in most organisation you need more than one of each. Products targeted to repeatable tasks are more efficient and accurate than custom code solutions and follow a more consistent
and defined approach in building t
Product solutions are continually developed and enhanced - which can be applied to existing creations. E.g. if Nintex Forms deploy an upgrade, all existing forms now have this functionality. There is no manual code updates required. That, and they are also
supported.
There is definitely a place for custom development in SharePoint, but for the purposes of quickly repeatable solutions such as forms & workflow, there should be a decent amount of analysis into requirements before taking the custom route.

What are disadvantages by using field catalogmerge in ALV

can any body tell the disadvantages by using field catalogmegre and maximun how many fields build the filed catalog.

Hi Diva,
I have gone thru the advantages... and don't see and disadvantage in building it thru functions....
The only advantage, that you can maintain dynamically during runtime, the structure of your ALV grid.
Mostly you are using static structures for ALV, so it is easier to create a static structure in SE11 and give this structure to your ALV_GRID_DISPLAY as a parameter.

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

From a practical perspective, besides the 64 bit version being a bit faster at just about everything, limitations on document size are lifted in the 64 bit version. Essentially, how much can do is limited only by how much RAM you have installed in your system. You can do things like have larger documents, deeper history, etc. and have it all work quickly.
On the other hand, many 3rd party plug-ins, especially older ones, only provide 32 bit versions, which will only run in 32 bit Photoshop.
Both 32 and 64 bit versions are installed by default. It's important to note that most of the preferences are separate between the two, so you can have two slightly different setups that might help with specialty operations you might need. This gets pretty subtle, but for example I keep the 32 bit version configured with only 1 cache level, so all previews of high bit depth images are always composited in high bit depth. This aids me with some aspects of astroimage processing. It's slower, but more accurate. By contrast I have more cache levels configured for my 64 bit version, so that's faster for general photography work.

What is the disadvantages of using Serialization?

HAi all,
I want to store objects in a file. I am preferred to use serialization. But I want to know what are the disadvantages of using Serialization over other methods (direct file, Keyed File)?
Can we store as many records using serialization? Is there any limit? Is there any security related issues?
Pls help me.
regards,
namanc

I don't think there is disadvantage using serialization compare to direct i/o access to file or any storage, except that you need to design your code such as it is serializable (hence, you may want to use transient keyword, or use externalizable, to be able to store/load the object properly).
Use serialization if possible, it saves you from inventing new+uncompatible mechanism of doing something in java.

Advantages and disadvantages of using views ???

Hi
What are the advantages and disadvantages of using views in ABAP porgramming ?
Thank You

hi,
Data about an application object is often distributed on several tables. By defining a view, you can define an application-dependent view that combines this data. The structure of such a view is defined by specifying the tables and fields used in the view. Fields that are not required can be hidden, thereby minimizing interfaces. A view can be used in ABAP programs for data selection.
More complicated views can comprise several base tables, the individual tables being linked with a relational join operation. If we dont specify the key fields, it takes time to fetch teh results.

Whats the advantage of using PSA instead of IDOC?

Hi,
Whats the advantage of using PSA instead of IDOC in transfer methods?
-Arun.M.D

Hi Arun,
PSA - Persistent Staging Area
IDOC - Intermediate Document
PSA is a temporary storing of all the data.
IDOC is used as a intermediate document to trnasfer the data from one system to our BW systems.
From PSA we can transfer 1600 bytes of data & by using PSA we can edit the data also.we can also rectify errors also through PSA,bcoz PSA is a subfunction of our SAP BW system.
IDOC we can transfer only 1200 bytes of data & we cant rectify the errors if any,bcoz it is not a function of SAP BW.

Disadvantages of using REFCURSORs from JDBC

Hi,
Normally I write my SQL statements from inside Java (eg PreparedStatements).
I am investigating on creating PL/SQL Packages, supplying procedures and methods, which I can call from Java using CallableStatements. I understand the advantages of having a layer/API on the database side.
For example: retrieve some records from a table. (the PL/SQL function getCustomers returns a REFCURSOR)
- PreparedStatement (select ... from ... where ...) -> executeQuery -> loop ResultSet
- CallableStatement ("begin ? := getCustomers(); end;") -> cast getObject() to ResultSet -> loop ResultSet
What are the disadvantages of using the CallableStatement (REFCURSOR)?
Thanks, regards, Stephan

While that article may be a good intro for someone not familiar with JDBC it has some misinformation in it that can be misleading at best and cause performance and memory issues at worst.
Row-prefetching - there is little benefit to using a large value for this setting. As with most things extremes are to be avoided.
It is important to know how the data is going to be used. What is the point of bringing ALL the data from the DB in one call if you are going to write it to the file system. File I/O is generally the slowest part of an application.
It is also important that the code be scaleable. Apps should be written so that future modifications will impact existing functionality as little as possible. If you eat up the memory for one table or statement that limits the memory available for other uses. Worse, when things go wrong and you need to reduce the fetch setting you may now have problems everywhere because the testing you originally performed may have relied on that larger fetch setting.
If the data fetching is not done in its own thread then using a very large value can actually make an application appear to 'freeze' while it waits for the data fetch to complete.
A large fetch size can also waste significant amounts of memory; essentially allocating it but never using it and never allowing any other process to use it. This is because for a fetch size of 'n' Oracle has to allocate space for 'n' rows that are each of maximum size.
This wasted is most often due to the common VARCHAR2 datatype. Consider a single column defined as VARCHAR2(100). In the DB this column is stored as variable length. But Oracle will allocate 100 characters (could be multi-byte characters) in order to be able to hold a maximum length value.
If the actual data values never exceed 30 bytes then 70 bytes in each row are totally wasted. The more rows that are prefetched the more memory that is wasted simply in anticipation of a maximum length value that never occurs or only occurs rarely.
I've never used a prefetch/fetch size greater than one thousand and that was for tables with small records (no more than 10 or 20 columns).
And the Oracle docs don't even recommend a setting that high. See the JDBC Dev Guide
http://docs.oracle.com/cd/B19306_01/java.102/b14355/oraperf.htm#i1043756
>
Oracle Row-Prefetching Limitations
There is no maximum prefetch setting, but empirical evidence suggests that 10 is effective. Oracle has never observed a performance benefit to setting prefetch higher than 50. If you do not set the default row-prefetch value for a connection, then 10 is the default.
